Answer:

We should add 1.2 fluid ounces of oil

Correct statement and question:

You are really excited to have found a Puch Maxi Moped from the mid Eighties, and the spring weather is making you want to get out and ride it around. It doesn't run on straight gasoline, you have to mix the oil and gas together in a specific ratio of 2.4 fl. oz. of oil for every gallon of gasoline. You have 2 quarts of gas. How much oil should you add?

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Ratio = 2.4 fl. oz. of oil for every gallon of gasoline

Amount of gas you have = 2 quarts

2. How much oil should you add?

Let's recall that 1 liquid gallon = 4 liquid quarts, therefore:

Ratio = 2.4 fluid ounces of oil for every 4 quarts of gasoline

Replacing the with the real amount of gas we have:

Ratio = 1.2 fluid ounces of oil for every 2 quarts of gasoline )dividing by 2 the oil amount and the gas amount)

We should add 1.2 fluid ounces of oil

damaskus [11]

Answer:

2 $\frac{1}{3}$ inches

Step-by-step explanation:

First, I would try to get the mixed numbers into improper fractions. Then, I try to make them have the same denominator so it is easier.

1 $\frac{1}{2}$ feet --- 2 inches

$\frac{3}{2}$ feet --- 2 inches

$\frac{6}{4}$ feet --- 2 inches

1 $\frac{3}{4}$ feet --- ? inches

$\frac{7}{4}$ feet --- ? inches

$\frac{7}{4}$ feet --- $\frac{7}{6}$ × 2 inches

= 2 $\frac{1}{3}$ inches

An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in California.

pishuonlain [190]

Answer:

The 80% confidence interval for the mean per capita income in thousands of dollars is between $21.3 and $21.9.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.8}{2} = 0.1$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.1 = 0.9$ , so $z = 1.28$

Now, find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

$M = 1.28*\frac{12.5}{\sqrt{3839}} = 0.3$

The lower end of the interval is the sample mean subtracted by M. So it is 21.6 - 0.3 = $21.3.

The upper end of the interval is the sample mean added to M. So it is 21.6 + 0.3 = $21.9.

The 80% confidence interval for the mean per capita income in thousands of dollars is between $21.3 and $21.9.
